I have code that automatically creates an image gallery from a simple array. It behaves like the applications which the gray overlay effect when opening a full size image. Note the "title" attribute, which sets the value for the size of the full size images.

No HTML names or IDs are used, greatly reducing the chance for conflict with an existing document and it doesn't use any JavaScript "framework."

A demo is here, using 6 of your images.

You may download the complete application, in a zip file, here:
